Descrição

Since the introduction of the D7E dozer, customers worldwide have saved millions of liters/gallons of diesel fuel and reduced overall emissions.* The D7E features an innovative diesel-electric power train that helps you save money by getting more work done while using significantly less fuel. Electric drive gives you the power you need for dozing, along with the smooth operation and agile maneuverability suited to a wide variety of applications. The new D7E meets Tier 4 Final/Stage IV/Japan 2014 (Tier 4 Final) emission standards. *Compared to the D7R2.
